Using scripts\treemap.php

gistfile1.txt

To known how to use it, just do `php scripts/treemap.php --help`.
By default, there is no analyzer defined, so to add them, create a configuration file and add in it:`
```
<?php

use mageekguy\atoum\scripts\treemap\analyzers;

$script
	->addAnalyzer(new analyzers\token())
	->addAnalyzer(new analyzers\size())
	->addAnalyzer(new analyzers\sloc())
;
```
And use it with `-c` argument.

Awesome! 👍

class members implements treemap\analyzer

    public function getMetricName()

    }

            {
                switch ($token[0])
                {
                    case T_PUBLIC:
                    case T_PRIVATE:
